Greetings Haskellers, Happy Thanksgiving! I'm using Ubuntu 9.10. I've performed the following steps: # apt-get install ghc6 I then successfully did a local install of the Haskell platform in ~/mine/install Now I am trying to get wxhaskell to install: $ cabal install wx [snip] Configuring wxcore-0.12.1.2... setup: Missing dependencies on foreign libraries: * Missing C libraries: wx_baseu-2.8, wx_baseu_net-2.8, wx_baseu_xml-2.8 This problem can usually be solved by installing the system packages that provide these libraries (you may need the "-dev" versions). If the libraries are already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are. cabal: Error: some packages failed to install: wx-0.12.1.2 depends on wxcore-0.12.1.2 which failed to install. wxcore-0.12.1.2 failed during the configure step. The exception was: exit: ExitFailure 1 $ ls /usr/lib/libwx* /usr/lib/libwx_baseu-2.8.so /usr/lib/libwx_baseu_net-2.8.so.0.6.0 /usr/lib/libwx_baseu-2.8.so.0 /usr/lib/libwx_baseu_xml-2.8.so /usr/lib/libwx_baseu-2.8.so.0.6.0 /usr/lib/libwx_baseu_xml-2.8.so.0 /usr/lib/libwx_baseu_net-2.8.so /usr/lib/libwx_baseu_xml-2.8.so.0.6.0 /usr/lib/libwx_baseu_net-2.8.so.0 It looks like the libraries are there to me! any ideas?
